The Mesozoic period began about 250 million years ago when the Permian-Triassic extinction occurred, probably by a combination of gradual atmosphere change and some external event like an Earth impact. The period ended about 66 million years ago with another great extinction, this one probably a combination of an impact and volcanic activity.
The permian period was the end of the paleozoic era.
The non-avian dinosaurs did not survive the mass extinction event at the end of the Mesozoic era, known as the Cretaceous-Paleogene extinction event. These reptiles went extinct, paving the way for the rise of mammals and birds.
The Cenozoic Era. This began 65.5 million years ago.
The meteorite collision at the end of the Mesozoic era led to widespread fires, dust, and debris in the atmosphere, resulting in a significant temperature drop and altered sunlight reaching the Earth's surface. This caused a mass extinction event, including the extinction of the dinosaurs and about 75% of all species, leading to significant changes in the Earth's biosphere and ecosystem dynamics.
The climate of the Cenozoic era was generally cooler and more variable compared to the relatively warm and stable climate of the Mesozoic era. The Cenozoic era experienced significant fluctuations in temperature, including periods of glaciation, whereas the Mesozoic era was characterized by a more uniform greenhouse climate.
Two major eras that ended with mass extinctions are the Permian-Triassic extinction event, which marked the end of the Permian period, and the Cretaceous-Paleogene extinction event, which marked the end of the Cretaceous period. These events had profound impacts on life on Earth, leading to the loss of a significant number of species.
The Mesozoic era began roughly 250 million years ago, and ended 65 million years ago. (This Era ended because of the K.T. extinction)

End of the Mesozoic era
The first dinosaurs evolved in the Mesozoic. At the end of the Mesozoic, all non avian dinosaurs became extinct. Therefor, all non avian dinosaurs, and some avian dinosaurs (birds), lived in the Mesozoic.
There were major asteroid impacts.
Mesozoic era
No. The dinosaurs rose in the Mesozoic era. The end of the Mesozoic era was also the end of the dinosaurs. The era following is the Cenozoic, which we are still in today.
